Tofall whom it may concern:

g Beit knownthat I, HARRY W. STIMsoN, a citizen of the United States, and resident of West Allis, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Tools, of which the following is a description, reference being had4 to the accompanying drawmgs, which are a part of this specification.

This invention relates to certain new and useful improvements in tools, and has for one of its objects to provide a tool especially adaptedfor use in removing scoring from cylindersremo.ving .the ridges therein after Ythe samehave been bored, and for any other pur ose desired where the tool will performr Vits nctions in a satisfactory manner.

' Another object of this invention is" to pro- I vide a tool of the kclass described so designed and constructed as to `permit its use immediately after a cylinder has been bored by f mounting the-same in a chuck carried by the tail piece of the lathe upon whichthe cylinderis being bored whereby the reamingV or polishing of the cylinder will be absolutely true with the bore thereof.

A further ob'ect of'this invention is to provide a tool o the class described in whichl the tool member pro er or. the abrasive carrying member "is yieldin lyor resiliently connected withthe tool ar or. Y

A still further object of this invention is to provide a tool of the class described having a plurality of tool members having means for simultaneously adjusting'the same with res ect to the axis of the tool arbor.

a ith the above and other objects in view -which will appear as vthe description proceedS, my invention resides inthe novel con.

struction, combination and arrangement of parts substantially as .hereinafter described and more particularly defined by the append- 4ed claims, it beingv understood that such changes in the precise embodiment of the herein `disclosed invention may be madeas y come within the scope of the claims.

In the `accompanying drawing I have illustrated one complete example of the physical embodiment of my invention, and a modification thereof, constructed according to thek best mode I have so far devised for the practical application of the principles "thereof, and in which:

, K'Figure 1 is a side view of a tool embodying my invention illustrating the samey as operating withln a cylinder shown in oon- Figure 3 is a fragmentary view part in section and part inelevation, of a slightly modified construction of my tool.

Referring now more particularly to the accompanylng drawing, in which like numerals designate like parts throughout the several views:

The numeral 5 designates a cylinder, shown 1n conventional lines in Figure 1, that 1s being worked upon to remove scoring or to ream the same by my improved tool which conslsts of an arbor having an enlar ed outer end l6 and an inner reduced eng 7 whlch entends throughout the major portion of its length. The part 6 carries the tool parts proper and the part 7 is engageable wlth a chuck or other holding member, not shown.

The outer end of the part 6 is provided wlth pairs of radially extending spaced ears or lugs 8 between which are pivotally secured the outer ends of links 9. The inner ends of the links 9 are pivotally secured, as at .11, to the inner projections 12 of fastenlng plates-'13. They fastening plates 13 are each 1n turn connected with a block or tool member 14 by fastenings 15, suitable yieldable or resilient means 16 being interposed between the fastening plates 13 and the members let whereby the members 14 are normally yleldably urged into engagement with the walls of the cylinder 5.

The blocks 14 may be, as before stated, the tool member proper or may form the holdlng means for a polishing or an abrasive member 17, as illustrated in the drawing. In the event that the members 14 form merely retaining blocks for the covering 17, they have their sides longitudinally channeled as at 18, in which a spring clip or othei` fastening member 19 is engageable to readily removably secure the covering in posltion.

The circumference formed by the outer faces of themembers ,14, may be readilyI adjusted to accommodate the tool for use in connection with cylinders of any size, and this adjustment is obtained by a cone member 2Q. mounted upon the part 6. In Figios ures 1 and 2, 'the cone member has a centrally threaded bore in engagement with the threads of the part 6 whereby thesame may be moved toward or away from the outer end of the arbor. Engageable with the inclined face of the cone member are pro jections or lugs 21 formed on the links 9 so that a movement of the cone 20 toward the outer end of the arbor will expand the same.

tool or a reverse movement will contract the The cone member 20 is readily re-l leasably secured in its adjusted position by a knurled lock nut 22.

In Figure 3 I have illustrated a slightly modified form, of my invention in which the yielding engagement of the tool members with the walls of the cylinder being worked upon is obtained by freely slidably mount-IA,

ing the cone member 20 upon the arbor shank 6v and confining a spring 23v between the cone member and the lknurlednut Y The adjustment of the tool is obtained by changing the position of the nut 22 to vary l the tension of the spring 23, and by this conthe arbor.

struction the engagement of the members 14' with the cylinder walls is'yieldable. If desited, in this form of my invention, the re-I silient member 416 may be dispensed 'with and the securingmembers 13 made fast with the blocks 14.

What I claim as myinvention is:`

1. A device of they class described, com- 'prising an link having a yieldable connectionI with the tool member, and means foradjusting the tool member with relation 'the' axis of 2. A device of the class described, com-1 t0 prising an arbor, a toolmember, a link hav-l bers, j a link ends pivotally arbor, a tool member, a link conv necting the tool member with the arbor,`said' ture.
